6 Claims.

This invention relates to new and useful improvementsin a transparent stamp display envelope and hinge.

The invention has for an object the construction of a transparent stamp display envelope which is adapted to be pasted or in a similar manner mounted within a stamp album so as to advantageously display the stamps, without damaging either the face, back or edge of the stamp.

Still further the invention proposed the provision of a lapel integral the sheet from which thel envelope is constructed and adapted to act as a hinge so that a portion of the lapel may be pasted down upon the album and the envelope itself may assume a at position against the page of the album or may be pivoted upwards so that the stamp may be removed if desired.

Still further the invention proposes arranging the envelope and hinge in such a manner that it is necessary to move the envelope about its lapel hinge so that its back-side is disposed to the front beforethe stamp may be removed.

Still further the invention contemplates so arranging the structure of the envelope that the lapel hinge may be disposed at the top or at the side.

vFurthermore as another object of this invention an arrangement is proposed whereby similar display envelopes may be connected together in a continuous shape.

Still further this invention contemplates an arrangement whereby the similar envelopes may be connected togethen in various adjusted relations, that is, either closer or farther apart.

Still further the invention proposes the construction of an article as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to' the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 12 is another similar view to Fig. 1, showing another application of the display envelope.

Fig. 13 is a similar view to Fig. 7, showing another modied form of the invention.

Fig. 14 is a. side view of Fig. 13.

The transparent stamp display envelope and hinge according to this invention comprises transparent sheet material in the form of an envelope having a front layer 10 and a rear layer 11 joined on all sides except one side designated by reference numeralr 12. This envelope is formed of cellophane or other similar material orv any transparent material which may be successfully bent and has suicient flexibilit The envelope itself is constructed from an integral sheet of material which is cut into a pattern and thereafter bent and pasted together to form the construction.' 90,

As illustrated, the front layer 10 is connected at its bottom edge with a rear bottom nap 13 which is pasted down upon a pair of overlapping sections 14 and 15 constituting the rear layer 11. These overlapping sections are pasted together along the overlapping. areas. The ap 13 is` pasted down upon the lower edges of the overlapping sections 14. The upper edge of the rear layer 11 is formed with a cutout 16 to facilitate removal of the stamp from the envelope. The dot and dash lines 17 schematically illustrate a stamp disposed Within an envelope. It should be noticed that a portion of the stamp extends from the cutout 16.so that it may be readily gripped and removed from place.

A lapel hinge 18 is integral with the sheet material which composes the envelope and projects from one edge of the envelope. As illustrated the lapel 18 is shown integral with and projecting from the top of the front layer 10. The lapel no 18 is formed with a reduced neck area 19 connecting with the head portion 20. This head portion is provided with gum or other adhesive material 21 which is arranged upon the front side thereof. The arrangement permits the lapel hinge 18 to be bent rearwards as illustrated in Fig. 3 and in this position the adhesive 21 may be wetted and the display envelope secured upon the page of an album. The stamp within the envelope may be easily seen through the transparent material and for this reason it is not often necessary to touch the stamp itself which would cause injury after age and continuous use. If for any reason it isdesired to remove the stamp from the envelope the envelope itself may be bent upwards around the hinge lapel and the stamp removed downwards through the open side 12 of the envelope.

In Figs. 4 and 5 a modified arrangement of the device has been disclosed in which a hinge lapel 22 is illustrated projecting from one side of the envelope instead of the top. This envelope is also formed from one integral piece of transparent material. It comprises a front layer 23 and a rear layer 24. The front layer is composed of one integral piece and the rear layer is formed from several connected flap portions. There is a lower flap portion 25 which is connected upon the lower edge of the front `layer 23 and which is pasted down upon overlapping sections 26 and 27 integral with the sides of the front layer 23 respectively. These overlapping sections 26 and 27 are pasted together along a small area 28 along the edge of the section 26. The lapel hinge 22 projects from the side of the section 27.

This arrangement allows the lapel hinge to be folded rearwards similar to the corresponding one illustrated and described relative to Figs. 1-3 inclusive. The hinge lapel is provided with a reduced neck portion 29 which connects with a head portion 30 provided with gum or an adhesive 32 upon its front side. Consequently when the lapel hinge is turned rearwards the gum will be immediately adjacent the page of a stamp album book or other sheet upon which the display envelope is to be attached. In Figs. 6 and 7 another variation of the invention has been disclosed in which a display envelope is shown formed from one integral sheet of transparent material arranged in the form of an envelope. This envelope is composed of a front layer 33 and a rear layer 34. The front layer 33 is of one integral piece of material. The rear layer 34 is formed of overlapping and pasted together flaps and sections. There is a bottom section 35 which is integral with the front layer 33 and which is pasted down upon the lower edges of the overlapping sections 36 and 37 integral with the sides of the front layer 33 respectively. These overlapping sections are pasted down along the overlapping areas thereof. Gum material or other adhesive 38 is arranged upon the rear layer 34 and is adapted to be wetted or in any other manner caused to adhere to the pages of the album book to display the envelope in place. rear layer 34 has a cutout 39 at the top edge to facilitate the removal of astamp Within the en- Velope.

In Figs. 8 and 9 another modified form of the invention has been disclosed in which provision is made for detachably connecting similar display envelopes with hinges according to this invention, together. The arrangement comprises an opening 40 formed in the rear layer of each of the similar display envelopes and of a width The substantially equal to the width of the neck of the lapel hinge and formed along the sides with a plurality of bendable projections 4l extended towards each other and similar to each other. This arrangement allows the head portion 20 of the lapel hinge to be folded into a reduced size so that it may be slipped through the opening 40 and also allows the bendable projections 41 to be bent upwards so as not to interfere with longitudinal adjustment of the envelopes relative to each other. After a desired position of the envelopes to each other has been obtained, then the bendable projections 4l are bent towards each other and the folded head portion 20 spread out which is possible since access may be had to the interior of the envelope through the open top.

" In Fig. 8 two similar envelopes are shown joined together, the head portion 20 of the lower envelope is shown engaged through the opening so that the neck portion thereof is in a position held against sliding by the lower two projections on the opposite sides of the opening 40. The envelopes may be secured together in other positions as allowed by the projections 4l.

In Fig. 10 another variation of the invention has been disclosed in which the same feature illustrated in Figs. 8 and 9 is shown applied to the form of envelope illustrated in Figs. 4 and 5. According to this form of envelope the rear layers of each of the envelopes is formed with horizontal openings 42 having a plurality of similar bendable portions 43 align the top and bottom edges. These openings and projections are adapted to receive and hold the head portion of the lapel hinge as previously described relative to Figs. 8 and 9.

In Fig. 1l another variation of the invention has been disclosed. This type of envelope may be used for displaying a pair of stamps.

The envelope shown in Fig. 12 may be used for displaying a block of four stamps or larger size stamps. In other respects, these envelopes are similar to that shown in Fig. 1.

The envelopes shown in Figs. 13 and 14 are similar to that shown in Figs. 6 and 7 except that the adhesive 44 is arranged upon the usual hinge 45 on the rear layer 34 of the display envelope.
